CORALVILLE — For the second time in less than a week, residents were forced out of their Coralville apartment building because of a fire.

Fire crews were called to 725 20th Ave. in Coralville, near the Hy-Vee, for a report of a fire before 5 a.m. Wednesday. Coralville fire prevention officer Orey Schwitzer said officials are investigating the possibility that work to clean up a previous fire at the building sparked the blaze.

“We can’t say that for sure, at this point we are looking into it,” he said. “We investigate all possibilities.”

Fire crews were called to the apartment building early last Friday morning for a fire, which sent multiple people to the hospital with smoke inhalation. The cause of the original fire remains under investigation, Schwitzer said.

The original fire did damage mainly to one apartment, which allowed some residents to move back in. Schwitzer said Wednesday’s fire will displace all residents for an undetermined amount of time.
